Which of the following could cause a Certkiller .com computer to automatically reboot?

A.
An overheating CPU.

B.
A five second power failure.

C.
Insufficient Memory.

D.
A new set of software installed.

Explanation:
Power failure would shut down the computer, not reboot it. Insufficient memory and possible faulty
software should merely produce an alert to the computer user. Overheating CPU, or in some
cases overheated memory, will cause random reboots whenever the CPU reaches temperatures
above the intended working temperature.
